Abstract: This is a combination accelerator and brake control mechanism wherein there is a single pedal serving both as the gas control and the brake control. The single pedal is pivoted on a pivot fixed in a base, the pedal extending through the vehicle floor board. Pressing with the foot on the superior or upper part of the single pedal controls the gas to the vehicle motor, pressing with the foot on the lower or inferior part of the pedal controls the brakes of the vehicle. A see-saw rod contacts directly or indirectly with the ends of both the vehicle gas control rod or the brake control rod, and the motion of the pedal pressed down on its top end acting through the see-saw rod moves the gas control rod from neutral position to gas control position, and pressing the lower end of the pedal actuates the brake control rod.
